This vehicle does not rely on anything but computer timing and fuel to stay running. With that in mind the computer relys on many sensors to judge the proper fuel mixture to keep the car running. The first place to look is the fuel system. If the pressure is low it may be the fuel pump or a blocked fuel filter. If the pressure is correct you would move on to checking the injectors. If all if right with the world on those two it becomes a bit harder. The engine timing relies on quite a few sensors, there is a sensor that replaces the distributor it can slip if the screw is loose and cause timing issues, there is the O2 sensors which from a cold start should hold the voltage high telling the car to provide fuel, it they hold the voltage short then the car will not provide enough fuel to keep the engine running.
You would need a tool to read the engine diagnostics, when you first start the truck the engine should report that it is in "open loop", and switch to "closed loop" when the O2 sensors reach the 600F operating temp that they need. If this does not happen check the sensors. If your tool does streams you can also pull a chart of the O2 output, at cold start it should be a straight line at the top of the chart, and switch to a sine wave with the average of the wave being zero once the system goes into closed loop.

Your describing symptoms of a bad Idle Air Control (IAC) motor. It's mounted on the top of the motor near where the intake tube enters. Does this have the 4.0L V6?

Suggestion, don;t try and start the car with the gas pedal pushed to the floor. Asking for trouble in the future.
Could be a fuel pump, clogged fuel filter.
Check engine light on? If so, Have the code read/scanned at your mechanic, or your local auto parts superstore.

check what the diagnosis machine will give if there is no data then check if the starter crank sensor is getting any power
